Yes we need a modinfo-like tool.
Currently, the UIO/VFIO binding can be done after parsing the PCI device list.
It is better to define the device ids locally to their drivers but it must
be integrated with an appropriate parsing tool at the same time.
And more importantly than any tool, the format of these ELF data must be
properly defined, documented and extensible.
Is there someone experimented with such format definition?
Stephen, you were asking for this change, what is your opinion?
I remember that Neil was also interested in this change:
Panu, Christian, this change could be related to distribution packaging.
Thanks for helping to move this change forward.
